Definitions

  • Device for enriching air with an air treatment agent in particular for air disinfection, air scenting and / or odor masking
  • the invention relates to a device for enriching air with an air treatment agent, in particular for air disinfection, air scenting and odor masking.
  • Air treatment is required, for example, in living rooms (e.g. of allergy sufferers), in office buildings, means of transport and transportation, hygiene areas and in healthcare.
  • Evaporators are known for air treatment, in which an air treatment agent is evaporated with the aid of an evaporation device. With such evaporation of the air treatment agent, the air is relatively strongly enriched with treatment agents, so that the treatment agent is deposited in the room to be treated. Precipitation of the air treatment agent cannot be avoided even by clocking an evaporator operating due to the supply of heat. The precipitation is only limited in time. The precipitation of air treatment agents on cold objects such as windows and the like. The like disturbs the user and also leads to easier soiling of these objects, since dust is attracted by the precipitation, for example. The precipitation on wooden furniture u. Like. Can also lead to damage to the furniture.
  • Spray-compressed air systems for spraying air treatment agents are also known.
  • a fine atomization of the Air treatment agent Even when using spray-compressed air systems, the occurrence of precipitation of the air treatment agent is not avoided.
  • Another area of application for air treatment agents is, for example, the introduction of disinfectants when cooling baked goods after the baking process. It must be avoided that mold germs are deposited on the surface of the baked goods before packaging. Since precipitation of the air treatment agent is also unacceptable in this area, complex air filter systems with different filter systems are used. The problem here is that the mold germs can be deposited in the air filter system and act as mold growth spots for the air filter itself. As a result, the filters have to be replaced frequently and cleaned very thoroughly.
  • Air treatment is also required for the storage of cheese after ripening, since after the ripening, mold growth in the air causes undesirable mold formation on the cheese surface.
  • cheese is covered with a covering agent, for example, which contains an antibiotic.
  • the antibiotic penetrates the outside of the cheese due to diffusions.
  • antibiotics are undesirably added to the human body when the cheese is enjoyed.
  • the use of filter systems in cheese preparation has the same disadvantage as in the preparation of baked goods.
  • the object of the invention is to provide a device for enriching air with an air treatment agent, in which the precipitation of the air treatment agent is avoided.
  • the device according to the invention has a storage container for holding liquid air treatment agent and an evaporation device connected to the storage container, for example via a pipe or a hose, for heating the air treatment agent.
  • a metering device is arranged between the storage container and the evaporation device, ie for example in the hose or tube. The metering device ensures a quantity-limited supply of liquid air treatment agent to the evaporation device.
  • a mixing container is connected to the evaporation device, in which the evaporated air treatment agent is mixed with air.
  • the mixing container has an outlet opening for discharging the mixture of air and vaporous air treatment agent.
  • the inlet openings in relation to the small amount of liquid air treatment agent supplied, so much air is supplied that it is possible to supply the room to be treated with an air treatment agent fraction per hour and cubic meter of air which is between 0.1 and 0.00001 ml is preferably between 0.01 and 0.001 ml. Due to this small amount of air treatment agent that is supplied to the room to be treated, no precipitation of the air treatment agent can be detected in the room. A disturbing precipitation on cool windows or the like does not occur.
  • the device of the invention is thus particularly for living rooms, waiting rooms and. Like. Suitable.
  • the air treatment agent portion is preferably less than 100 ppb (parts per billion) and in particular less than 10 ppb.
  • the mixing container is preferably assigned a means for generating an air flow, such as a fan. Air is sucked or blown into the mixing container by the fan through the air inlet openings provided in the mixing container. Furthermore, the means for generating an air flow serves to expel or blow out the mixture of air and vaporous air treatment agent from the outlet opening.
  • an amount of 0.01 ml per cubic meter per hour to 0.005 ml per cubic meter per hour of air treatment agent is supplied to the room to be treated.
  • a space of, for example, 50 cubic meters of air 0.5 ml per hour to 0.25 ml per hour are thus fed from the storage container to the evaporation device and evaporated therein.
  • the conveying capacity of the agent for conveying the air stream must not be too great.
  • a relatively high delivery volume is required to achieve an extremely low proportion of air treatment agents per cubic meter of air.
  • the volume flow of air conveyed is preferably 25-35 m 3 per hour.
  • the ratio between the amount of air conveyed and the amount of air treatment agent supplied to the evaporation device is thus in the range from 140/1 to 50/1, preferably 100/1 to 70/1.
  • the at least one air inlet opening of the mixing container is larger in cross section than the at least one outlet opening. If there are several outlet or several inlet openings, the sum of the cross-sectional areas of the outlet openings is smaller than the sum of the cross-sectional areas of the air inlet openings. In a preferred embodiment of the invention there is a continuous supply of air treatment agent to the
  • the metering device preferably has an outlet opening, through which the air treatment agent exits in the direction of the evaporation device, the cross-sectional area of which is less than 0.078 cm, in particular less than 0.000314 cm. With a round outlet opening, this corresponds to a diameter of 0.1 mm or 0.2 mm. It is preferably a fixed, non-variable outlet opening. The diameter of the outlet opening can be varied, for example, by changing the corresponding disk or the like in which the outlet opening is provided.
  • pane or the like with a relatively large outlet opening and to reduce the amount of air treatment agent which is supplied to the evaporation device by providing panes with smaller outlet openings in the flow direction in front of or behind the pane with large air outlet openings.
  • insertion slots for inserting such panes can be provided, for example, in a tube or hose arranged between the storage container and the evaporation device.
  • the storage container is preferably arranged opposite the evaporation device in such a way that there is a difference in height between these two parts of the device, the storage container being arranged higher.
  • the fluid connection such as the hose or the tube
  • the evaporation device preferably has a temperature of 40-70 ° C.
  • a peristaltic pump or another suitable conveying means for conveying the air treatment agent.
  • air treatment agents are preferably conveyed continuously.
  • the amount of air treatment agent depends on the one hand on the delivery volume of the fan and on the other hand on the size of the room to be treated.
  • continuous delivery it is also possible to supply the air treatment agent to the evaporation device at intervals. This has the advantage that conventional, low-cost peristaltic pumps can be used.
  • the storage container preferably has a pressure compensation device, so that ambient pressure and no negative pressure always prevail in the storage container. Negative pressure would influence the amount of air treatment agent that is supplied to the evaporation device.
  • the storage container is preferably closed with a lid or the like.
  • the lid which can be removed for filling the storage container, preferably has a particle filter.
  • the particle filter is designed such that air can flow into the storage container for pressure equalization, but on the other hand prevents particles such as dust from getting into the storage container. Such particles can clog the metering device or impair the flow rate.
  • the pressure compensation device which is preferably an opening provided with a particle filter, is preferably provided in the cover. However, it can also be arranged at a different location on the storage container.
  • a second preferred embodiment of the invention for enriching air with an air treatment agent also has a storage container for holding liquid air treatment agent and an evaporation device connected to the storage container for heating the air treatment agent.
  • This preferred embodiment of the invention has an inclined evaporation surface of the evaporation device. The air treatment agent flows over this inclined evaporation surface.
  • a return device is connected to the evaporation device, which returns the non-evaporated air treatment agent to the storage container.
  • a thin film of air treatment agent thus preferably forms on the evaporation surface of the evaporation device, so that uniform evaporation of the air treatment agent takes place over the entire surface of the evaporation surface.
  • the provision of a return device through which excess air treatment agent is collected and returned to the storage container means that the amount of air treatment agent that is fed to the evaporation device does not have to be determined so precisely. Rather, the amount of air treatment agent that evaporates and is supplied to the air to be treated essentially depends on the temperature of the evaporation surface of the evaporation device. The amount of air treatment agent that is supplied to the air to be treated can thus be easily adjusted by regulating the temperature of the evaporation surface. Furthermore, the device according to the invention has the advantage that, due to the preferably continuous flow of the air treatment agent over the evaporation surface, no deposits are formed on the evaporation surface. The efficiency of the evaporation device can be impaired by deposits. It is also necessary to clean the evaporation device regularly. Such cleaning is at the device according to the invention is not required or at most only at very large intervals.
  • the inclination of the evaporation surface which is preferably arranged in one plane, is preferably 10 ° to 30 ° with respect to a horizontal. An inclination of 15 ° to 25 ° is particularly preferred.
  • the evaporation surface preferably has transport grooves running in the flow direction of the air treatment agent.
  • the second embodiment of the invention preferably has a mixing container designed in accordance with the first embodiment of the invention described above.
  • a means for generating an air flow such as a fan, is preferably arranged within the mixing container.
  • the arrangement of the fan below the evaporation device is particularly preferred, so that the air flows past the evaporation device and is thereby enriched with evaporated air evaporation means.
  • the arrangement of the fan below the evaporation device has the advantage that the evaporation surface is not cooled too much by the air flow generated by the fan, so that the desired evaporation rate is maintained.
